Charlie's Angels Season 3 Episode 16 Disco Angels

When the third victim of the bus strangler is found, Charlie's Angels are called in to investigate. Two leads turn up; the victims were disadvantaged older men who rode the bus home at night and all were last seen in the vicinity of Freddie's Disco. The Angels concoct a cover, enabling them to question suspects in disguise. They suspect Disco owner Fred (Freddie) Halston, dance shill, Mario Montero and Freddie's D.J., Harry Owens. Further investigation rules out Freddie and Mario. Kelly questions Harry Ovens in his apartment. His lecherous intentions are cut short by his father's arrival, a meeting Harry had forgotten. The father berates Hardy, his job and his station in life, leaving Harry visibly shaken. Kelly informs the Angels of her suspicions about Owens. When they approach Harry's glass D.J. booth at the Disco, they find the music automatically controlled and Harry's voice pre-recorded. The suspect is nowhere to be found.
